specmeation of Letters Patent. Patented Apr. 19, 1910.

Application led February 28, 1908. Serial No. 418,328.

To all whom it may concern:

Be it known that I, EDWARD PossoN a citizenv of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Car-Ventilatore, ofwhich the following is a specification.

The object of my invention is to provide an improved ventilator adaptedfor use on railway cars.

It is also my object to provide a ventilator that shall be operated bythe movement of the car through the outside air.

These objects and others will be made apparent in the followingspecification and claims, taken in connection with the accompanyingdrawings, in which- Figure 1 is atop plan view of an ordinaryrefrigerator car, showing my invention applied thereto. Fig. 2 is alongitudinal .section taken on the line 2, 2 of Fig'. 1. Fig. 3

Fig. 11 is an elevation of anauxiliary damper, which is shown in its relation to the other parts inFig. 2. Figs. 12 and 13 are sections taken on the correspondinglynumbered lines. in Fig. 11. Fig. 14 is a sectional plan view of apassenger coach, showing my invention applied thereto. Fig. 15 is alongitudinal section taken on the line 15 of Fig.' 14. Fig. 16 is asectional plan View taken on the line 16 of Fig. 15. Fig. 17 is atransverse section of the passenger car ventilator taken on the line 17of Fig. 16.

The reference numerals20 and 21 refer,

respectively, tothe roof and running board of a refrigerator car.Underneath the running board 2l, a pair of longitudinal chairnels 22 and22a extend from the end of the car, one of them going to near the middleand the other a less distance, where theyi turn downwardly and openintothe car, as indicated by 'the reference numerals 23 and 23a.vSimilarv channels extend from the other end of the car, but are notshown in the drawings. At the end, these channels 22 turn sidewise, asindicated by the reference numeral 24. The ice boxes 25 at each end ofthe car are separated from the main interiorof the car by the partitions26. The opening or hatchway 27 extends 4upwardly from the compartment 25and through this opening the ice may be dropped down into saidcompartment. A closure or plug 28 is provided which tit-s tightly intothe pas` sage 27, the walls of the latter converging downward. This plug28 has handles 34 by which it may be raised and lowered and is securedfrom being lost or removed t0 a distance by means of the chain 35.

The reference numeral 29 refers generally to the outer hood or cover forthe passage 27. This has the shape of a rectangular box and is hinged at30. Adjacent to the hinge are braces 31 on the hood vwhich c0- act withblocks or stops 32 on the car to prevent the hood 29 from opening backmore than is desirable. These parts and their relation are clearly shownin Fig. 2.

The reference numeral 33 indicates generally an opening provided with adamper by which the brano passages 24, previously referred to, lead intothe passage 27 above the plug 28 and below the hood 29. T he hood 29 hasa lip or flange all around 1ts lower edge and wlthin this is a softpacklng material 37. Around the upper edge of the opening 27 is aprojecting lip 38 on which the said packing 37 rests, thus givmg thehood 29 a tight fit over the passage 27 .On the opposite side ofthe-hood from the hinges 30 is a handle 39, and also a locking device40, by which the hood may be locked in closed position.

Referring more particularly to Fig. 4,it'

is to be observedthat the hood 29 has the form of a rectangular box, thefront and rear sides of which are open as indicated by the referencenumerals 41 and 42. Within the box 29 are vertical partitions 94, 95, 96and 97, 4which converge in pairs from the sides of the respectiveopenlngs 41 and 42 toward the center of the box. Thus, extending fromthe opening 41 there is la passage Which converges` to the point 43, at

which point the side walls are so dezdected that the passage iscontinued at right angles into the part designated as 45. Sinn.- larly,from the opening 42, the passa-ge converges to 44 and is there turnedthrough 46. Doors 47 and 48 are hinged horizontally across the loweredge of the openings from the respective passages 45 and 46. As shown inFig. 4, the door 47 is opened out horizontally while the door 48 is in avertical closed position. Beyond these doors are the respective openings49 and 50 on the sides of the box 29. In the bottom of the box 29 thereare four openings 51, 52, 53 and 54 which communicate with the spacebeneath, that is, with the passage 27. From the respective openings 51and 52 the passages 56 and 57 lead alongsidey the passage 45 andterminate at the door 47. Similarly,

from the openings 53 and 54 lead the pasf sages 58 and 59, whichterminate with the passage 46 at the door 48. The two doors 47 and 48are connected by a link 60 which is pivoted to each. The intermediatepart of this link is bent aside, as indicated by `the reference numeral61, in order to avoid the vertical rod 72, the purpose of which will beexplained later. A khole 63 is cut through the partition 944-97 andthrough this the link 60 extends. ln the bottom of the box 29 there is acircular opening 62. A' damper, to be explained presently, lies acrossthis opening and at its top the said opening connects with the openings51, 52, 58 and 54, which have been described.

The damper which lies across the opening 62 is illustrated in Figs. 7,8, 9 and4 10. This consists of two fixed opposite quadrantal sectors 64and 65united by the part 98. Beneath them are two similar movablesectors 66 and 67, which are fixed to the lower end of the central shaft7 2. Between the xed sectors 64 and 65 are sector-shaped open spaces 68andl 69. @n top of the box 29 a quadrant 76 is attached, its centerbeing on the axis of the shaft 7 2, the latter extending verticallythrough the box.' The edge of the quadrant 70 carries pairs cinpstanding lugs 71. A crank 78 extends radially across the quadrant 70,being iixed to the aforesaid shaft 7 2 and having a transverse hole atits outer end which carries a ring 74, wherebyit may be manipulated.

This crank 7 3 has enough :dexibility so'that its outer end can belifted over the lugs 71. Thus, by shifting the crank 7 3 on top of thebox 29, the damper 66-67 may be adjusted on the under side of said box.

Referring now particularly to Figs. 11, 12 and 13, the damper in thewall of the passage 27 will be described. The position of this damperwith relation to the other parts is shown in Figs. 2 and 5, where it isceases indicated by the reference numeral 33. lt

consists of a fixed member 83 with a series of rectangular openings 75vand a slidin member 76 with corresponding openings 77 adapted toregister therewith. There is a series of notches 78 at the bottom of aterminal xed opening 75, and a lug 79 on the end of the sliding member76 is adapted to engage one of said notches. rllhere is .a handle 80 onthe slidingI member 76 and the latter has enough play in its guides 81so that the lu 79 can be lifted out of any one of the noto es 78 whenthe sliding member l76 is shifted.

The modification illustrated in Figs. 14, 15, 16 and 17 is a ventilatorspecially adapted for use with a passenger coach. Fig. 14 shows how itmay be placed with reference to the other parts of the coach, theventilator being indicated by the reference numeral 82. Figs. 15, 16 and17 have the parts corresponding to those described in connection `withthe earlier figures, numbered the same.

ln this case the damper in the vertical passage 27 is of a dierent type,being adapted for operation from below. A lever` arm 84. hangs downthrough the opening 83 and is pivoted at 85. Carried integrallytherewith is a damper slat 86. Similar slats 87 are held in parallelismtherewith bymeans of the connecting link 89, which is pivotally attachedto the several slats 86, 87 at points 88. Shifting the lever arm 84opens and closes the slats 86, 87, as will be obvious. To preventcinders or dirt from coming into the passenger coach, if from any causethere should be a transient down draft through the ventilator, a screenor network 90 is rovided above the damper. In this modi cation the rod60 is straight, the partition being slightly odset, as indicated by thereference numeral 91, to give an opening therethrough. rlhe box or hood29 is shown as stationary in this case, there being no need to open itback as there is when it forms the door for the ice chamber of arefrigerator car. its top and bottom walls are 92 and 93, respectively.

Referring to either modification, when the car is traveling along thetrack at any considerable speed, the air will be caught in the forwardopening 41 or 42 and will draw back through the passage 43-45 o'r thepassage 44-46, according to the direction of ravel. If the door 47 or 48at the end ofthe passage happens to be closed, the pressure of the airwill open it and in sodoing will close the door at the end of theopposite passage by means of the link 60. Thus, reerring moreparticularly to Fig. 4, supposing the train to be traveling to the left,the air will rush through. the passage 41-43-45, discharging from theopening duits 22 from the interior of the car.

49. As it issues from the end of the passage 45, it will tend to drawthe air out of the adjacent passages 56 and 57 by an ejector action, andthus the air will be drawn into the last named passages, up from belowthrough the openings 51 and 52. In the case of the refrigerator carillustrated in Figs. l and 2, the air will be drawn along the con- Inthe case of the passenger car, the air will be drawn from under the carceiling adjacent to the ventilator.

W'hen it is desired to put ice in the ice chambers 25, the ventilatorhood 29 may be turned back, the closure 28 removed and thus the passage27- to the ice chamber is free and unobstructed. Either or both of thedampers illustrated in Figs. 7 to 12 inclusive may be employed. It willbe understood that the damper 33 can be adjusted only when theventilator hood 29 is thrown back, while the other ventilator can beadjusted from the top 92 of the hood 29. Aftery filling the ice chamber,the hatch covers can be sealed down, thus making it impossible forpilferers to get through the hatchways to the interior of the car. Allnecessary adjustment of the damper can be made from the outside by meansof the handle 73-7 4. In the passenger coach ventilator only one damperis provided, that being shown in Fig. l5.

It'will be seen that I have provided a ventilator for refrigerator carswhich draws the air from the body of the car. Thus, the air which iowsinto the car to take the place of that drawn out has a tendency to comefrom the ends, where it is-cooled by the ice. But my ventilator is ofwider application, including its use on a passenger car, as shown.Stated broadly, my ventilator comprises. two conduit-s, one having bothends open to the atmosphere and adapted to have a current y set uptherein by movement through the surconstitute an ejector.
